That's pretty impressive, in a slightly different way to the one I had expected. What was the program logic? Just looking through all the possible alternatives at each stage, to the 1st/2nd/3rd/nth degree and applying some sort of evaluation function to 'em?

Given that you can beat a Nokia 7110, you can't be a bad player - so to program something which could beat you is rather good going!

It was fairly straightforward - look for the move that gives you the best score, to a depth of 1 or 2 moves (and assuming that the opponent makes their best move by the same rules), plus some weightings for certain squares - edges are good, corners are better and moves that would allow your opponent to gain a corner/edge are bad.

The 7110 isn't particularly strong - with very little coaxing, it would leave corners open at an early stage, allowing me to fairly easily build up large unassailable blocks.
